,To an whom it may concern:

Be it known that I, EUGENE SCHNEIDER, citizen of the Republic of France, residing at Le Creusot, Sadne-et-Loire, France, have invented certain new and useful Improvements in- Incendiary Projectiles, of which the following is a specification.

This invention relates to incendiary projectiles that are adapted particularly for firing balloons and the like. According to the present invention the incendiary charge ignited by the flame coming from the fuse, is arranged in anannular cylindrical or prismatic housing formed in the body of the projectile around an axial tube, the upper end of which communicates with the fuse and which itself serves as a housing for an igniting charge, while its lower extremity forms a guide for a piston for forcing out the base plug:

In order that the said invention may be clearly understood and readily carried into effect, I will describe the same more fully with reference to the accompanying drawing, in which:

- Figure 1 represents in longitudinal section on the axis of the projectile an embodi- .ment of the invention applied to a projectile furnished with a slow-match. Fig. 2 is an elevation partly in section of a similarprojectile furnished with a common time In these figures a is the body of the projectile on the ogival head of which a slowmatch (Fig. 1) or a common time fuse (Fig. 2) is screwed. In the body of the projectile an annular cylindrical or prismatic housing is formed for the incendiary charge 0 throughout its entire height. This housing is limited laterally and externally by the Wall of the body of the projectile and interwasher or disk is retained in the projectile by its outer edge by means of a ring it screwed to the rear end of the projectile body a. v

The axial tube 03 forms a housing for an igniting charge 2' which may be confined between a shoulder g of the inner wall of the tube and a piston f guided in the tube. This piston may be rigid with the plug 6 or may merely rest upon it with its rear end. At the rear end of the tube at recesses or orifices r are formed and opposite these an igniting washer 8 may be incorporated in the incendiary charge. At the' front part of the tube n'a housing 25 is formed for a ball or other non-return valve; 70 is a plug formed with an axial passage and u is an orifice placing the housing tvand the interior of the tube at in communication.

a designates a primer composition at the rear end of the fuse; m (Fig. '1) is a compressed block producing retardation of the transmission of the flame.

0 (Fig. 2) is an ordinary fuse ring and m designates a percussion system of any known construction.

The incendiary shell described operates in the following manner :-When the projectile is fired the supporting disk g is fused or burned and no longer opposes the expulsion of the base plug e; the striker a: strikes the detonator y and the flame is transmitted by the retarding block m (Fig.1) or by the intermediary of the fuse ring 0 (Fig. 2) to the primer composition it carried by the fuse and then through the axial tube to the igniting charge 2' contained by the latter. The gases of this charge 2' first of all act upon the piston f which they force out together with the base plug a. Before the piston f has completely issued from the central tube (Z the gases enter into communication with the incendiary charge through the apertures r formed in the tube. and ignite this charge which burns during the whole or a portion of the trajectory of the projectile. The obturating ball j in obturating the passage in the plug is serves to prevent the gases from the igniting charge from spreading outside through the communications of the fuse.

That I claim and desire to secure by Letters Patent of the United States is 1. In a projectile, the combination of a fuse, an incendiary charge, a hollow member communicating at one end with the fuse,

associated with said hollow -..member and explosive force of fuse, an incendiary charge,

'mem er, a ried by said hollow member and engaging said base plug and slidable. to open coman igniting charge and a movable element associated with said hollow member and controlling communication between said igniting and incendiary charge.

2. In a projectile, the combination of a fuse, anincendiary charge, a hollow mem ber communicating at one end with the fuse, an igniting charge, and a movable element mit communication between said igniting and incendiary charges through said apertures and to remove said base plug. 6. In a projectile, the combination of a fuse, 'a hollow member communicating at one end with said fuse, an igniting charge associated with. said hollow member, and an obturating device automatically operated to close the passage fuse after the former has been ignited. 7. In a projectile, the combination of a fuse, a hollow member communicating at one end with said fuse, an igniting charge carried by said hollow member, turating device her and automaticallyoperated to close the passage between sai, ",harge and fuse after the former has been .gnited. 8. In a projectile, a fuse, a movable memher, a base plug associated with said movable member, a disk contacting said b. is plug, means holding said disk in; position,

operated by the explosive force of said 1gniting charge to permit communication between said igniting and incendiary charges.

In a projectile, the combination of a fuse, an incendiary charge, a hollow niem ber communicating at one end with the fuse, an igniting charge, a base plug, a movable element associated with said hollow memher and said base plug and operated by the said igniting charge to open communication between said igniting and incendiary charges and to remove said base plug.

4. In a projectile, the combination of a fuse, an incendiary charge, a hollow member communicating at one end with the fuse, an i nitin charge carried by said hollow ase plug, a movable element carmovable member to remove and disk.

9. In a projectile,

said base plug a fuse, a hollow memengaged by said piston, a disk engaging said base plug, means holding said disk and plug in position, and a charge the explosive force of: which drives said piston to remove said plug and disk.

In testimony whereof I have alfixed my signature in presence of two witnesses.
